Window balances

Question

Unfortunately I can't provide photos of these installed as they both fell out of the window a long time ago. Markings say, "25 4 BL Caldwell." I can provide more photos of different angles if needed.

Thanks for posting. I believe this might be an S380-26 or S385-26 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, or the heel-to-toe measurement. See below. Measure your old balance's shoe to see what matches best. For a stamp option choose 2540.
